40 shapes challenge sheet

I've made the sheet available as a pdf here
This is a great challenge for any version of logo (Scratch, Snap! etc.). Snap is better since you can make blocks to avoid screen clutter.

This comes from Barry Newell's book "Turtle Confusion: Logo Puzzles and Riddles" (1988). It can be used as a series of challenges. Depending on the class I've usually found that some scaffolding for some of the shapes is required for some students.

I have developed other worksheets which either
  •  provide scaffold or tips for some of the shapes, eg. with shapes 6 and 7 it is best if the turtle starts and finishes in the centre; then a genuine shape 38 is not too hard (there are 36 vertices in shape 38)
  • enrichment, eg. develop block code with variables for shapes 1, 2 and 5 (rather fiddly for shapes 3 and 4 so I left them out for this part)
